I have made a PC (5e) Artificer's Armorer subclass from UA that has the Dual Wielder (DW) feat. What happens when the PC is in the guardian mode and equips a shield?
When you take the Attack action and attack with a light melee weapon that you’re holding in one hand, you can use a bonus action to attack with a different light melee weapon that you’re holding in the other hand. You don’t add your ability modifier to the damage of the bonus attack, unless that modifier is negative.
Dual Wielder Feat:
You gain a +1 bonus to AC while you are wielding a separate melee weapon in each hand. You can use two-weapon fighting even when the one handed melee weapons you are wielding aren’t light. You can draw or stow two one-handed weapons when you would normally be able to draw or stow only one
Your gauntlets are weapons that due to the DW feat can be used for an off-hand bonus action attack.
If you equip a shield, are you still qualified to perform this bonus action off-hand attack, as your offhand is both a weapon and a shield?
You qualify for the +1AC, as you are wielding 2 separate weapons. Is the +1AC from the DW feat still applicable when you equip a shield?
